OSHKOSH, Wis. (AP) — Divers have recovered the body of the Green Bay Packers’ offensive coordinator’s son from an icy Wisconsin River, but police said Tuesday they do not suspect foul play.

Michael Philbin, 21, disappeared at about 2 a.m. Sunday after an outing with friends in the University of Wisconsin-Oshkosh campus area, about 50 miles from Green Bay.

Police had been searching the Fox River since Sunday evening, after a security guard reported hearing cries for help from someone on the ice. Divers found his body near the campus on Monday. He is the son of offensive coordinator Joe Philbin.

An autopsy was scheduled for Tuesday. Results are not expected for at least a month. Oshkosh Police Chief Scott Greuel said Tuesday they suspect no foul play.

Grueul said they delayed releasing Philbin’s identity out of respect for his family’s privacy and because there’s no threat to public safety. Greuel declined to release any details of how Philbin became separated from his friends, saying the investigation continues.
